Quoting Tris <[EMAIL PROTECTED]>:
Hi all..
when I started PHP (5 years ago.. or maybe 4... I forget) I learnt
that to create a varaiable, I simply wrote:
$variableName = "variableValue";
OR
$variableInt = 3;
All good, it's worked for years..
Buuuuuut....
During myturningon errors today, I was seeing LOADS of undeclared
variable errors..
so I simply added to the top of each page, the problem variable names,
and a blank value.. eg:
$date = "";
$userName = "";
$score = "";
thus declaring them for later use...
Now this strikes me as a pain in the back side..
Can anyone throw lighton to why I need to do this, OR can I fix the
undeclared variables 'bug' without having a list of blank variales at
the top of each page...?
I don't think that you have to do this, I think it's just considered
good practice. In a language that uses strict data typing (C#, C and
Java, I'm looking at you...) then it makes sense to declare them at
the start of the code, however I've always init'd variables as I use
them and I've never had any real issues...
My £0.02,
Matt
